Functions

func GoName2Cxx added in v0.17.0 

func GoName2Cxx(name string) string

GoName2Cxx translates a fully-qualified Go type name to a C++ one. e.g.:

  • go-hep.org/x/hep/hbook.H1D -> go_hep_org::x::hep::hbook::H1D

func NewGenGoType(pkg string, sictx rbytes.StreamerInfoContext, verbose bool) (*genGoType, error)

NewGenGoType generates code for Go types from a ROOT StreamerInfo.

func StreamerOf 

func StreamerOf(ctx rbytes.StreamerInfoContext, typ reflect.Type) rbytes.StreamerInfo

StreamerOf generates a StreamerInfo from a reflect.Type.

func Typename added in v0.17.0 

func Typename(name, title string) (string, bool)

Typename returns a language dependent typename, usually encoded inside a StreamerInfo's title.

func Visit added in v0.17.0 

func Visit(ctx rbytes.StreamerInfoContext, si rbytes.StreamerInfo, f func(depth int, se rbytes.StreamerElement) error) error

Types

type Element added in v0.17.0 

type Element struct {
	Name   rbase.Named

	ArrDim int32      // number of array dimensions
	MaxIdx [5]int32   // maximum array index for array dimension "dim"
	Offset int32      // element offset in class
	EName  string     // data type name of data member
	XMin   float64    // minimum of data member if a range is specified [xmin.xmax.nbits]
	XMax   float64    // maximum of data member if a range is specified [xmin.xmax.nbits]
